The province of Buenos Aires has taken a significant step in the development of wave energy in Mar del Platawith the first technical test of a device designed to transform the waves of the South Atlantic into electricity. The equipment, which will be installed in the North breakwater of the Mar del Plata portIt aims to become the first real-scale experience of its kind in Argentina and a benchmark for other coastal projects.
This development, driven by the Ministry of Infrastructure and Public Services through the Buenos Aires Province Undersecretariat of Energy, it is part of a broader strategy to diversify the energy mix with renewable sources and of local technological origin. Although the project is located on the Argentine coast, the advances in this type of solution They are generating interest in Europe, where countries with coasts exposed to the Atlantic waves are studying similar initiatives.
How the Mar del Plata wave energy device works
The heart of the system is relatively simple to understand: it is based on large floating buoys that rise and fall with the movement of the wavesThis vertical oscillation is mechanically transferred to a set of arms and gears that convert the oscillation into high-speed rotation, which allows an electric generator installed in the structure to be operated.
According to the design developed by the engineering team of National Technological University (UTN) Buenos Aires RegionalEach device is designed to achieve a power output of between 30 and 200 kilowattsThe final figure will depend on the size of the buoy used, the configuration of the mechanism, and the intensity of the waves in the area where the system is located.
The mechanism is completed with a structural arm and a transmission system These components withstand the forces generated by the sea and transfer that energy to the generator. The selection of robust mechanical components is key to ensuring the equipment can operate for extended periods with minimal maintenance, which is especially important in marine environments.
One of the peculiarities of the chosen solution is that most of the technology is of national developmentFrom engineering design to manufacturing of the main parts, this allows the device to be adjusted to the specific conditions of the South Atlantic and, potentially, to replicate the experience on other coasts with similar characteristics, including areas of Europe with strong ocean dynamics.
The first test in Pilar: “dry” test and structural validation
Before entering the sea at Mar del Plata, the team underwent a static test in the Buenos Aires town of Pilarat the Duroll metalworking plant. This was carried out far from the coast to allow for precise control of loading and safety conditions.
During the verification, it was applied to the device a load of 1,5 tonsThat is, approximately double the stress it is estimated to withstand in actual operation when subjected to waves. The objective was to verify the strength of the main arm, the resistance of the buoy, and the overall behavior of the structure under stresses exceeding those anticipated.
The results reported by the Undersecretariat of Energy were considered satisfactory by the technical teamThis allowed for the validation of the structural design and progress to the installation phase in the port. This type of preliminary testing is common in energy projects in both Latin America and Europe, as it reduces the risk of failure once the systems are exposed to real marine conditions.
Following this initial mechanical validation, the project enters a stage where elements such as the anchoring to the breakwater, the safety systems and integration with the electrical grid. Although it is currently a prototype, the experience gained will be used to improve future versions and assess its potential scalability.
Installation on the North Breakwater of the port of Mar del Plata
The device will be mounted on the North breakwater of the port of Mar del PlataOn the waters of the South Atlantic, an area where sea movement is constant and waves are often significant for much of the year, this location will allow the technology to be tested in a demanding environment, but with good generation prospects.
The choice of the breakwater is based on several factors: on the one hand, the proximity to port infrastructure It facilitates assembly, maintenance and network connection tasks; on the other hand, it minimizes interference with regular navigation routes and takes advantage of existing structures to fix the device.
The Buenos Aires provincial government has emphasized that this prototype is not intended solely as a local demonstrator, but as a milestone for the national industryCombining academic research, applied engineering, and metallurgical production with Argentine suppliers. This type of public-private collaboration is similar to that seen in wave energy projects in European countries with a tradition in marine energy.
Alongside the physical installation, a phase is planned of detailed monitoring of equipment behaviorThis is important both in terms of electricity production and response to storms and changes in wave patterns. The data collected will be essential to determine the system's actual performance and economic viability, as well as to draw lessons applicable to other coastlines, from the Galician Atlantic to the Cantabrian Sea or the Portuguese coast.
Project financing and institutional coordination
The development of this wave energy technology in Mar del Plata has a specific financing of $138.000, contributed mainly through the Provincial Program of Incentives for the Generation of Renewable Distributed Energy (PROINGED)This is a scheme that uses funds linked to the electricity tariff to promote innovative distributed generation projects.
In addition to PROINGED, the device receives support from Buenos Aires Technological Innovation Fund (FITBA) and the Scientific Research Commission (CIC)These organizations participate in the evaluation, monitoring, and technical support. This combination of public instruments aims to facilitate the transition from applied research to implementation in real-world settings.
The role of National Technological University, in particular its Buenos Aires Regional branch[Name of person/entity] has been central to the team's design, contributing expertise in mechanical engineering, structural calculations, and gear system optimization. The collaboration between the university, government, and private sector is one of the project's highlights and aligns with European initiatives where coastal technology campuses have become testing grounds for wave energy solutions.
The provincial administration insists that the objective is not just to test a prototype, but generate own industrial and technological capabilities that can then be adapted to other marine environments and the needs of different territories, including foreign markets. If the experience proves successful, the cooperation model and the lessons learned could serve as a basis for alliances with European stakeholders interested in competitive wave technologies.
Advantages of wave energy compared to other renewables
This greater regularity allows for a more accurate estimation of the future electricity productionThis is highly valued when planning energy systems and managing the grid. In practice, having a more predictable renewable energy source facilitates the integration of generation into the grid without needing to oversize backup or storage systems.
In the case of the South Atlantic, the characteristics of the waves make it an interesting setting for this type of testing. Similarly, in Europe, areas such as the Spanish Atlantic coast, the Portuguese coast or western Irelandwhere the sea presents comparable conditions in terms of wave energy. The experience of Mar del Plata can provide useful information for these contexts, especially regarding structural robustness and continuous operation.
Another relevant advantage is that, being generally near the coast or on port infrastructureWave energy devices can be connected to the grid without requiring extensive underwater cables. This reduces certain infrastructure costs and simplifies maintenance, an aspect also considered in European pilot projects.
Future prospects and possible applications in Spain and Europe
Although the Mar del Plata device is still in the early stages of prototype and validationIts development provides lessons that may be useful for other countries interested in wave energy. In Spain, for example, the Cantabrian and Atlantic coasts They have been the subject of studies and pilot projects to evaluate wave energy potential, with special attention to integration with the naval and port industry.
The approach adopted in Buenos Aires, based on a robust mechanical design, dedicated public funding, and university involvementThis is similar to what has been seen in European initiatives in Scotland, Portugal, and the Basque Country. Sharing data on performance, operating costs, and behavior during storms could accelerate the maturation of this technology on both sides of the Atlantic.
In an energy transition scenario, where the European Union has set ambitious targets of decarbonization and increased renewablesWave energy is emerging as a potential complement to solar and wind power. Experimental projects like the one in Mar del Plata serve to test on the ground whether these solutions can achieve a reasonable cost and reliability comparable to other established renewable technologies.
If the Mar del Plata experience confirms their production expectations in the range of 30 to 200 kW per device And if the operation proves to be stable over time, it would not be surprising if international collaborations emerged in the areas of design, manufacturing and commercial exploitation, including European actors with experience in marine energy.
Overall, the advancement of the device wave energy in Mar del Plata This is a clear example of how the combination of applied research, local industry and institutional support can pave the way for new forms of renewable generation in coastal areas, with potential future synergies for European regions that share the same challenge: to efficiently and sustainably harness the energy that arrives every day in the form of waves.
